Hello everyone. It's been a while since I posted. But I think I'm the only person on here with 20 inch rims/tires and thought I'd let you know that I've had my wheels on for 2 years now with no problems. 22's won't fit the front but they will fit in back. I have a 70' that I drove cross country to Cali from GA. I didn't put them on until I got here though. lol!
But if you are like me and only CRUISE in your Monte, I dont think it will be a problem. If you are a daily driver, I recommend no bigger than 18's.
